A method and apparatus for uplink transmission over a non-contentious shared feedback channel are disclosed, wherein the parameters of the uplink transmission are determined by the parameters of a downlink transmission. A new uplink channel, called a physical shared uplink feedback channel (PSUFCH) is used for uplink transmission such as feedback information in response to a downlink transmission on a fast shared data channel. The content of the feedback information may be general, e.g. an ACK/NACK or a channel quality indicator (CQI). The PSUFCH is transmitted using power ramping that terminates upon reception of a downlink ACK (DLACK) from a Node-B. No ambiguity resolution is required due to the non-contentious and deterministic mapping of the uplink channel resources.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A wireless transmit/receive unit (WTRU) comprising: a processor and a transmitter configured to for one or more transition time intervals: select between transmission of: (1) acknowledgment/negative acknowledgment (ACK/NACK) information with channel quality information (CQI) and (2) the ACK/NACK information without the CQI, as a selection, wherein the selection between the transmission of the ACK/NACK information with the CQI and the transmission of the ACK/NACK information without the CQI is based on higher layer signaling; generate a signal using one of: (1) the ACK/NACK information with the CQI or (2) the ACK/NACK information without the CQI in accordance with the selection; and transmit the generated signal, to a network entity, (1) on physical uplink channel resources which carry data on condition that the ACK/NACK information with the CQI is the selection and data is being sent, and (2) on the physical uplink channel resources which do not carry data on condition that the ACK/NACK information without the CQI is the selection and no data is being sent.
A wireless device transmits acknowledgement (ACK/NACK) information, sometimes with channel quality information (CQI), to a network. The device decides whether to include CQI with the ACK/NACK based on instructions from the network. The device then transmits the combined or separate ACK/NACK signal. If the signal includes CQI *and* the device is sending data, it transmits on uplink channel resources allocated for data. If the signal includes *only* ACK/NACK and no data is being sent, it transmits the signal on physical uplink channel resources which do not carry data.
2. The WTRU of claim 1 , wherein a physical uplink channel that includes the physical uplink channel resources is shared by a plurality of WTRUs.
The wireless device described in the previous transmission sends its ACK/NACK and CQI on a physical uplink channel that is shared by multiple wireless devices.
3. The WTRU of claim 1 , wherein the transmitter is further configured to transmit a request for uplink bandwidth on a physical uplink channel that includes the physical uplink channel resources.
The wireless device described in the previous transmission also sends requests for uplink bandwidth on a physical uplink channel, that includes the physical uplink channel resources where the ACK/NACK/CQI is sent.
4. The WTRU of claim 1 , wherein transmissions on a physical uplink channel that includes the physical uplink channel resources have a varying number of bits.
The wireless device described in the previous transmission sends data on a physical uplink channel, that includes the physical uplink channel resources where the ACK/NACK/CQI is sent, where the amount of data (number of bits) sent varies.
5. The WTRU of claim 1 , further comprising a receiver configured to receive physical channel resource parameters used for transmissions on a physical uplink channel that includes the physical uplink channel resources.
The wireless device described in the previous transmission also contains a receiver. This receiver obtains parameters from the network. These parameters define how to transmit on a physical uplink channel that includes the physical uplink channel resources where the ACK/NACK/CQI is sent.
6. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising: for one or more transition time intervals: selecting between transmission of: (1) acknowledgment/negative acknowledgment (ACK/NACK) information with channel quality information (CQI) and (2) the ACK/NACK information without the CQI, as a selection, wherein the selection between the transmission of the ACK/NACK information with the CQI and the transmission of the ACK/NACK information without the CQI is based on higher layer signaling; generating a signal using one of: (1) the ACK/NACK information with the CQI or (2) the ACK/NACK information without the CQI in accordance with the selection; and transmitting the generated signal, to a network entity, (1) on physical uplink channel resources which carry data on condition that the ACK/NACK information with the CQI is the selection and data is being sent, and (2) on the physical uplink channel resources which do not carry data on condition that the ACK/NACK information without the CQI is the selection and no data is being sent.
A wireless device transmits acknowledgement (ACK/NACK) information, sometimes with channel quality information (CQI), to a network. The device decides whether to include CQI with the ACK/NACK based on instructions from the network. The device then transmits the combined or separate ACK/NACK signal. If the signal includes CQI *and* the device is sending data, it transmits on uplink channel resources allocated for data. If the signal includes *only* ACK/NACK and no data is being sent, it transmits the signal on physical uplink channel resources which do not carry data.
7. The method of claim 6 , further comprising sharing, by the WTRU, a physical uplink channel that includes the physical uplink channel resources with a plurality of other WTRUs.
The wireless device, as described in the previous transmission method, shares a physical uplink channel that includes the physical uplink channel resources where ACK/NACK/CQI is sent with other wireless devices.
8. The method of claim 6 , further comprising transmitting a request for uplink bandwidth on a physical uplink channel that includes the physical uplink channel resources.
The wireless device, as described in the previous transmission method, also sends requests for uplink bandwidth on a physical uplink channel, that includes the physical uplink channel resources where the ACK/NACK/CQI is sent.
9. The method of claim 6 , further comprising transmitting on a physical uplink channel that includes the physical uplink channel resources the generated signal having a varying number of bits.
The wireless device, as described in the previous transmission method, transmits on a physical uplink channel, that includes the physical uplink channel resources where the ACK/NACK/CQI is sent, and the data has a varying number of bits.
10. The method of claim 6 , further comprising receiving physical channel resource parameters used for transmission on a physical uplink channel that includes the physical uplink channel resources.
A wireless device (WTRU) dynamically manages its uplink transmissions. During specific time intervals, the WTRU selects whether to transmit acknowledgment/negative acknowledgment (ACK/NACK) information *with* Channel Quality Information (CQI) or *without* CQI. This selection is based on higher-level network signaling. Once the selection is made, the WTRU generates a corresponding signal. This signal is then transmitted to a network entity. If ACK/NACK with CQI is chosen and user data is currently being sent, the signal is sent over physical uplink channel resources that concurrently carry the user data. However, if only ACK/NACK (without CQI) is chosen and no user data is being sent, the signal is transmitted on physical uplink channel resources specifically designated for control information, which do not carry user data. Crucially, the WTRU *receives physical channel resource parameters* from the network. These parameters define the configuration and allocation of the physical uplink channel resources used for these transmissions.

11. The WTRU of claim 1 , wherein the processor is configured to, based on broadcasted information, set a format of a physical uplink channel that includes the physical uplink channel resources to a selected one of a plurality of formats such that a number of bits for transmission over the physical uplink channel varies based on the selected one of the plurality of formats.
